Those are my tires I just had Joe post the pic. The tires work really well stock, but they really woke up once I start doing some grooving. I'm actually planning on grooving some more lateral grooves for sidehilling, cornering, Etc.

Where exactly are you putting the duct tape?

On the inside bead of the wheels. 3 wraps of Gorilla tape is what I'm running with good results.

The radial would be better hands down but the tire would probably weigh at least 20lbs heavier, at least in the 44” version.

close to 5lbs a tire. I took pics before and after on the scale but since I don't have a star anymore I cant post pictures. grooved tire + beadlock weigh just under 60lbs total

Gentlemen, I bought an ideal groover and I want to either groove my tires of just sipe them. I’m leaning toward siping them, i daily drive and wheel the truck all year and don’t want to lose too much tire life, or make them shitty for summer wheeling. But I’m thinking everything I do will help for all year traction

. If I flip the blade upside down on the ideal groover, will that be enough? Just straight sipes? Most snow tires have sipes that are like this /\/\/\ but I don’t know how to achieve that efficiently.

I have these tires


Where is the best place to sipe them and or groove them? Which direction on which lugs? If grooving is the way to go, I will do that.


Groove the big center lugs and sipe them all?

Those look pretty good grooved up but I might try them stock first. I think the biggest drawback is that square edge on the tread. Maybe not though. No scientific research to confirm but I think it makes a stress point in the contact patch and breaks through the crust.

These tires actually didn’t do too bad on the ice as they are. Just siping may be all they need. When at 7 psi they squish out pretty well, 5 will be better. But there was lots of dry stuff so I couldn’t go too low this weekend.



Got my groover too, going to sipe them and see what works.

For what it’s worth everyone has different ideas, but for snow grooving I tend to use a #2 blade in my ideal groover which gives more of a heavy sipe than a groove. I use the #4 inverted for siping which works well. I’m just in the process of hitting my iroks up for this winter.

i would use a #2 blade and follow the stock siping the tires came with; looks like a good pattern.

Alright. I did 2 last night and came up with this. #4 blade I grooved the center lugs and siped everything. I followed the factory “siping”

Ok I finished the rest and added some grooves on the outer lugs to give a couple more edges.



Can’t see the siping yet but I think it will open up a bit.

We got a sad inch of snow but I went out anyway. Wanted to see how these tires hook up on slick stuff. They work pretty well. I almost want to groove them a little more.

Here’s a little clip of me going up a little hill that others has been spinning up. I crawled up this and some even steeper stuff no problem.

I met some cool guys snow wheeling, and they had some shit that worked really well. The first pic is some grooved Nitto MGs that worked really good, I noticed the groove pattern basicly turns each lug into smaller knobbies. So pic #2 is my SX grooved out, these will be snow only tires.

On a 2nd note about groovers, I borrowed a Ideal, and have compared it to my my Fein multitool. I preheated the ideal, it does good on a shallow groove, like 1/4", but for a deep groove it really struggled. I tried heating the lugs, and noticed after the first cut the lug was pretty warm already. My SXs are not new so the rubber is probably harder than normal.
So on to the multitool, I built a couple blades by taking a worn out fine tooth fein blade, heating a narrow line across it with a torch, bending it into a U shape, reheating it to RED and quenching it in ATF, then sharpening the edge on a belt sander.
Comparing it to the ideal, which I would say does about 1" per second. The multitool is crazy fast. On a shallow groove like 1/4"-3/8" it goes so fast I was accidentally cutting the next lug. And on a deep groove, 1/2"-3/4" it was still double the speed of the ideal.
I will say a couple of the first blades I made for the fein were not nearly as fast as the most recent Ive made, Blade length (front to back) doesnt seem to have an effect on the speed, only thing I can think of is that I belt sanded the whole blade to polish it up, maybe less friction.

Have any pics of how you’ve made the blade and of it attached to the tool? Now I’m curious

Also is that 89snowplow? Looks like his rig before he painted it blue

The blade on the tool is actually broke, but still works good, I think the hardening process made it brittle, and broke after cooling off. Only downside is I usually sharpen the backside too, so you can cut pulling the tool tword you also. The 2nd blade was made to have a more square cut.
I dont know about 89snowplow, all I know he lives in eastern OR

I had to google it to find out how it works. Interesting. Great idea if you have one of those tools but they’re twice the price of an ideal. But if it’s also way faster it’s worth it. Very cool.

Its got a tone of uses, windshield knife, sander, undercutting door jambs for floor covering, removing grout.

What is my best option to make these tires better on side hills? I noticed they do have a bit of a weakness there.

I was thinking maybe adding some more grooves. I have #2 and #4 grooving heads now. I used #4 for all my grooving so far.

What are the thoughts on grooving like this with my #2 head, so the groover would be smaller.
